When operating this equipment, use good judgment and safety precautions to avoid damage to equipment and property or injury to personnel.  \nBe sure you understand and follow the procedures and safety precautions contained in the chiller instructions as well as those listed in this guide.  \n\n| |  DANGER | |\n| --- | --- | --- |\n| Failure to follow these procedures will result in severe personal injury or death.\u003Cbr>DO NOT VENT refrigerant relief valves within a building. Outlet from rupture disc or relief valve must be vented outdoors in accordance with the latest edition of ANSI/ ASHRAE 15 (American National Standards Institute/ American Society of Heating, Refrigerating, and AirConditioning Engineers). The accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation.\u003Cbr>PROVIDE adequate ventilation in accordance with ANSI/ ASHRAE 15, especially for enclosed and low overhead spaces. Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, unconsciousness, or death. Misuse can be fatal. Vapor is heavier than air and reduces the amount of oxygen available for breathing. Product causes eye and skin irritation. Decomposition products are hazardous.\u003Cbr>DO NOT USE OXYGEN to purge lines or to pressurize achiller for any purpose. Oxygen gas reacts violently with oil, grease, and other common substances.\u003Cbr>NEVER EXCEED specified test pressures. VERIFY the allowable test pressure by checking the instruction literature and the design pressures on the equipment nameplate. DO NOT USE air for leak testing. Use only refrigerant or dry nitrogen.\u003Cbr>DO NOT VALVE OFF any safety device.\u003Cbr>BE SURE that all pressure relief devices are properly installed and functioning before operating any chiller. RISK OF INJURY OR DEATH by electrocution. High voltage is present on motor leads even though the motor isnot running when a solid-state or wye-delta mechanical starter is used. Open the power supply disconnect before touching motor leads or terminals. |  |  |\n\n\n|  WARNING | |\n| --- | --- |\n| Failure to follow these procedures may result in personal injury or death.\u003Cbr>DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure.\u003Cbr>To remove a component, wear protective gloves and goggles and proceed as follows:\u003Cbr>a. Shut off electrical power to unit.\u003Cbr>b. Recover refrigerant to relieve all pressure from system using both high-pressure and low pressure ports.\u003Cbr>c. Traces of vapor should be displaced with nitrogen and the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic gases.\u003Cbr>d. Cut component connection tubing with tubing cutter and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system.\u003Cbr>e. Carefully unsweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch flame.\u003Cbr>DO NOT USE eyebolts or eyebolt holes to rig chiller sections or the entire assembly.\u003Cbr>DO NOT work on high-voltage equipment unless you are a qualified electrician.\u003Cbr>DO NOT WORK ON electrical components, including control panels, switches, starters, or oil heater until you are sure ALL POWER IS OFF and no residual voltage can leak from capacitors or solid-state components.\u003Cbr>LOCK OPEN AND TAG electrical circuits during servicing. IF WORK IS INTERRUPTED, confirm that all circuits are deenergized before resuming work.\u003Cbr>AVOID SPILLING liquid refrigerant on skin or getting it into the eyes. USE SAFETY GOGGLES. Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes, IMMEDIAT","cbCaiiIO7k4XUoLb","https://ap.wps.com/l/cbCaiiIO7k4XUoLb","pdf",15054105,212,"English","# SAFETY CONSIDERATIONS\n## DANGER\n## WARNING","[{\"question\":\"为什么不能在建筑物内排放制冷剂泄放阀？\",\"answer\":\"如果未按要求进行，将导致严重的人身伤害或死亡。泄放口应在室外按 ANSI/ASHRAE 15 最新版本进行排放，以避免在密闭空间中造成缺氧窒息。\"},{\"question\":\"拆卸部件时需要遵循哪些关键安全步骤？\",\"answer\":\"先关闭机组电气电源并将制冷剂回收，使系统压力降至零。用氮气置换蒸汽并确保良好通风，避免明火造成有毒气体，同时使用割管工具切断连接并妥善接住可能外泄的油。\"},{\"question\":\"离心式冷水机的泄放装置需要多久检查一次？\",\"answer\":\"应至少每年检查一次泄放装置、爆破片以及其他泄放相关部件。若在腐蚀环境中运行，应更频繁地进行检查，并在发现腐蚀或异物堆积时更换装置。\"}]","AquaEdge - PIC II Controls - Start-Up, Operation, and Maintenance Instructions | PDF",1792713115,534]
